Application fi1ed June 19, 1926. Serial No. 117,207.

Our invention relates to frames for cloth boards and similar articles.The type of cloth board for which these frames are intended is that inwhich the frame is of generally open structure, includingside and endmembers, with or withoutone or more intermediate cross pieces, and iscovered with a tightly applied tubular envelope which .is usually paperof substantial thickness, this envelope covering the broad faces andlongi tudinal edges of the frame. In this type of board, if the frame isproperlyconstructed and the envelope properly applied, they will.mutually reenforce each other and produce a board or winder havinggreat strength and stiffness and other desirable characteristicsreferred to later. i

An important object of the. inventionis to provide a frame which isinherently very stiff and strong, and highly resistant to strainsappliedto it in'the operation of winding fabric upon it or in handlingthe cloth bolt so produced, and is also especial-V ly adapted forco-operation with the paper envelope which additionally strengthens andreenforces the frame, in the manner above referred to.

Another object is to provide a frame and also being especially adaptedfor simple and easy assembly with the cross pieces,

either byhand operations or partly or entirely automatic machinery, onereason for this adaptability being the symmetrical cross sectional formof the members which admits of their application to the cross pieces inany rotative position. 1

Another objectistov provide end cross-' pieces of improved form,including end portions which overlap the ends of the side' members andresist inward thrust applied by the chucks of the winding machine, theseends being contoured to match the semicylindrical contour of the sidemembers, and

the outer faces of theend cross-pieces be ing smooth, flat and flush toproperly red I ceive and maintain end labels in proper condition; andfurther, to provide improved interlockingformations on the end piecesand side members, which produce joints which are very stiff andresistant to angular deformation of the frame and are also devised toadmit of easy and'accurate assembly, either by hand or machineoperations;

A particular object is to provide a struc ture which admits of the use,in certain cases, of tubular paper side pieces, which are probablythemosteconomical devicesthat can be I material,and to realize at the sametime some vor all of the other objectsor advantages above and hereaftermentioned.

The characteristics and advantages of the invention are furthersufliciently explained in connection with the following detail de 'SCIlpliOIl of the accompanying drawing,

which shows representative embodiments of the invention. Afterconsidering these eX-I amples, skilled persons will understandthat manyvariations may be made, and 1' contemplate the employment of anystructures that employed for this purpose, in connection with crossmembers of'wood or analogous are properly within the scope of theappended claims. 7 V.

In the drawings: 7 r Fig. 1 is a perspective view of a frame embodyingthe invention in one form.

Fig. 2 is a fragmentary view,- partly in section in the longitudinalcentral plane.

Fig. 3 is a plan view of a frame of modiiied structure. 7 i

Fig. 4; is a sectionaldetail thereof; The invention contemplates theemployment of side members 1, Fig. 1, or 1, Fig.

3, which are of symmetrical and preferably circular cross section, andwhich may be either of tubular section, as 1, or solid section, as 1*;and which may beof paper or analogous fibrous composition, as 1, whichrepresents a standard 'or special form of papertube, which is astructure consisting of several turns or laininations of fibrous sheetmaterial, suchas chipboard, pulp board or other .paper stock, eitherstraight-wound or spiral-wound, with suitable adhesive as a binder orstrengtheningmaterial, or may be as at 1*, of wood or analogousmaterial.

In combination with such side members we employ cross pieces includingthe end pieces 2, Fig. 1, or2, Fig, 3, and when necessary,

depending on ;the lengtlr'of-the frame. or other conslderatlons, one ormore mtermed1ate cross pieces 3, Figs. 1 and 3. De-

sirably ,-these cross pieces areof wood .or,

analogous material, but in the broader aspect of the invention arenot solimited,an d may be of other material.

In each form of frame, the side and send members have connecting orinterlocking formations, which have generally similar characteristics inthentwo forms, but are specifically.different. Thus, in both forms, the.ends'ofthe end pieces are semi-cylindrically rounded .asat; tto conform,to the semi-round formation of the side pieces, and these portionsof.theendin-embers overlap V the ends ofv the side pieces so that thesmooth, I

rounded contourof thehoardedges in no broken both along the side membersand the the. side members and resist any inward .stralns-apphed to theend pieces.

These boards areplaced 111 winding machines wh ch 7 havechucks orvholders which exert strong end pressure on the end pieces tending topush them inward, and these strains are directly transferred by the endportions 4 to the ends of the side members and evidently theiend piecescannot be displaced inward except by' complete crushing of the sidemembers, which-are amply strong to resist the pressure.

W'hen thecloth boards are so placed in the winding machine, they arerevolved to, wind the fabriconthe board to form a bolt, and thefabric isplaced under tension, whichis often, very considerable, involving severestrains uponthe boardor its. frame structure, and the present frames areamply strong and sti fi to resist even the heaviestw vinding teusion, aswillsufficiently.appear from further description.

Afcomrnon characteristic of the end and sidepiece connection in bothforms of frame, isthatthe respective pieces have interfittingformations, or dowel .and socket formations,

providing a strong and secure interlocking connection, and the endpieces also have 'wall formations engaging substantial segments of theends 'of theside members, to provide ad ditional stifine ss at thecorner joints. 7 Thus, inFi'g's. 1 and2, the'end pieces are cut (by asuitabletool,such as a hollowvbit) to provide integral dowels, theseextending from annular shoulders 7 about the outer segments of thedowels, these shoulderscontinuingintopart-cylindrical slots 8 separatingthe dowels from walls 9 of the end pieces, thesewalls'being-substantially semicylindrical and terminating in edges 10 whichare flush with end segments of the side members. Otherwise stated,theseedges 1O constitute ends of. the inwardportions .of the flat faces11, which are tangent. to the surfaces of the side.pieces. The dowelsand the walls 9 are dimensioned to have a sub stantially tight slidingfit into and about the ends .of the side members, assufficientlyunderstood in Fig. 2, so that the: parts firmly interlock,and usually glue is applied before assembly, toinsure permanentconnection. zVhen theparts are connected the dowels of substantiallength fitting in the side members and .the bearing of theinner'segments of the side members of substantial area,

against walls 9, providea very strong and stiff brace against angularorother distortion of the frame and board.

To facilitate assembly, desirably,'the ends of the dowels are rounded orbeveled as at 12, and the inner edges of walls 9 are also tapered orbeveled asat 18, so that the tu bular side members are easily andpractically automatically guided intopositionin the assemblingoperation. This is especially important in assembling the parts withanautomatic or other machine in which it is only necessary toapproximately position the respective parts, whereupon they are broughtinto proper engagement by inward move ment of the end pieces in relationtothe side members. a, V

In the form ,SllOWItllTFlgS, 3 and 4, where the side members aredesirably of solid section, they are formed with end dowels 15,whicharedesirably more or less tapered as shown, these dowels beingsurrounded by annular shoulders 16. The end pieces 2 have the innerfaces of their ends formed with flatcircular areasl? to'co-operate' withshoulderslG, the inner contour of these faces being defined by walls 18of semi-cylindrical form to co-operate with inner segments of the sidemembers, as the-Walls 9 doin the previous example. Centrally inthecircular formations 17, sockets 20 are provided, generally formed tofitthe dowels 15-' or somewhat deeper than the dowels. V The dimensionof the wall 18 lengthwise of the board isdesirably greater than thelength of the dowel 15,"-so that in assembling theparts the side membersmay be moved laterally until segments of the full-diameter end-portionsof these members engage inward segments of the walls 18,whereupon thedowels are aligned with the sockets 20 and the parts may then be fullyinterlocked by-inward necessary for the sake of structural strength, 7comprising tubular paper side members of movement of the end pieces inthe lengthwise direction of the board, whereupon the,

are in engagement with walls 18 and the.

parts are braced against diagonal, twisting and other strains, as in theprevious case. Glue. is also usually applied to any or all of theengaging surfaces before they are brought together.

The intermediate cross pieces 3 are not subject to strains causingdisplacement lengthwise of the board, and therefore it is suflicient tomake their thickness equal to the outer diameter of the side pieces andto provide in their ends, semi-cylindrical sockets 21 to fit the innercontours of the. side members. Glue is also usually applied to securethe cross members against accidental displacement.

While the dimension of the end members in the longitudinal direction ofthe frame, from the ends of the side members to the outer faces 5, or inother words, the longitudinal thickness of the end portions 4, may

vary, this dimension, as indicated at A, Fig. 2, is usually greater thanwould be and'may originally be, for example, as indicated at a. This isto allow sufficient thickness of the-end pieces in the longitudinaldirection of the board to provide for variations which often occur inthe width of the cloth to be wound thereon. The width of clothfrequently varies as much as extra thickness provided, if the cloth runsnarrower, narrow slabs of proper thickness may be cut off from the endpieces or one of them, as indicated infull and dotted lines, in Fig. 2.This enables the textile manufacturer or finisher to easily conform theboard length to variations in width of the fabric without keeping onhand a range of slightly-varying board size for this purpose.

the provision of the fiat, smooth end faces 5 for the reception of endlabels, and it will be noted that even when substantial slabs are cutfrom the end pieces, as, and for the reasons above mentioned, thesmooth, continuous, fiat surface for label reception is still I tour ofthe side members, the side and end 50 As above stated, animportantfeature is Y members also having interfitting dowel and fsocket formations, the end members also having segmental wallsco-operating with.

substantial inward end areas of the side members to provide additionalcorner bracing.

2. A frame for cloth boards or winders substantial wall thickness andend members having portions overlapping ends of the side members andcontoured to agree with the outer contour of the side members, the sideand end members also having-interfitting dowel and socket formations,the end members also having segmental walls cooperating withsubstantialginwa'rd end areas of the side members to provide additionalcorner bracing.
